摘要 Sediment deposition in the pumping station has a huge negative impact on unit operation. The threedimensional CFD method has been used to simulate inlet structure flow in pumping station based on the Eulerian solid-liquid twophase flow model. The numerical results of the preliminary scheme show that sediment deposition occurs in the forebay of pumping station because of poor flow pattern therein. In order to improve hydraulic configuration in the forebay, one modified measure reconstructs water diversion weir shape, and another measure sets a water retaining sill in the approach channel. The simulation results of the modified scheme prove that back flow in the forebay has been eliminated and the sediment deposition region has also been reduced.
